Title: Improvements in or relating to the preparation of uranium silicide articles
Inventor: ACCARY ANDRE
IPC: C01B33/06
Filed: 1960-05-20
Abstract: <PICT:0908941/III/1> <PICT:0908941/III/2> Shaped articles of uranium silicide are prepared by heating an intimate mixture of U and Si particles in a mould under vacuum to at least 450 DEG C. but below the fusion temperature, e.g. 625 DEG -675 DEG C. for 1 hr., and setting the coherent porous product by heating under vacuum at a higher temperature, e.g. 1400 DEG -1550 DEG C. to obtain a non-porous product.  The second stage heating is preferably carried out, out of the mould and may, as the product is a conductor, be effected by passage of an electric current, or by induction.  The U and Si mixture in the proportions for the required silicide are compacted in graphite mould 1 by vibration to apparent densities 5,8, 5,6, 4,4, or 3,7 for U3Si2, Usi, USi2 or USi3 respectively. The mould 1, which tapers from the centre towards each end, and is made up of sections joined by force-fitted collars 3, is placed in stainless steel tube 4.  When the pressure in tube 4, which is connected through assembly 5 to a vacuum pump, is 10-5 mm. Hg, it is placed in tubular resistance furnace 9.  The silicide rod B is cooled, removed from the mould and placed in silica tube 10, which is connected to vacuum through 11 and mounted on movable carriage 13.  Fixed induction coil 27 heats the rod, and relative displacement of the carriage to the coil ensures that the hot zone travels through the rod.  Fixed tubular resistance furnaces 26 ensure absence of an excessive temperature gradient in the rod. U3Si is also referred to in the Specification.

Title: Improvements in or relating to cathode ray tubes
Inventor: CALLICK ERIC BRIAN BUTLER
IPC: G11C11/23
Filed: 1961-05-19
Abstract: 947,197. Cathode-ray tubes. ENGLISH ELECTRIC VALVE CO. Ltd. April 6, 1962 [May 19, 1961], No. 18282/61. Heading H1D. A cathode-ray tube has a large area cathode 2, Fig. 1, and two grid systems 5, 6 and 7, 8, each composed of mutually transverse arrays of conductors, the conductors being so energized that the first grid system permits only a selected portion of the beam to pass while the second grid system allows through only a small fraction of this selected portion of the beam. While various apertures of the second grid system are suitably positive to allow passage of the beam only the one aperture which is within the compass of the first selected portion of the beam is effective. In this way the number of external connections is reduced and to reduce the number still further the conductors of each grid system are interconnected in such a way, e.g. as in Fig. 4, that only a minimum of external connections are required. Preferably, the apertures of the two grid systems are of the same size so that the area of the first grid system through which the beam is permitted to pass embraces a number of apertures, the conductors of this grid system then being connected together in groups. The tube target may be a fluorescent screen, a system of Faraday cages for providing positionally determined output signals or a signal storage system.

Title: Improvements in and relating to generating plants for vehicles
IPC: H02J7/16

Abstract: 943,783. Self-contained supply systems with variable-speed generators; protective arrangements. ROBERT BOSCH G.m.b.H. May 19, 1961 [May 21, 1960], No. 18311/61. Heading H2H. [Also in Division H1] A supply system comprises an A.C. generator having windings 11, 12, 13 and a field winding 14 and being connected through rectifiers 16-18, 22-24 and 43 to a battery 44 and load 51. In the cooling bodies of the rectifiers 22, 23, 24 are mounted thermistortype resistor elements 35, 37, 38 made of semiconductor material and connected in series with the control coil 39 of a relay having a voltage coil 41 and normally-closed contacts 47, 48 connected across the winding 14. As the alternator is run up to speed its voltage is built up by the residual magnetic field of the armature and the current through its shuntconnected winding 14, until the pull of coil 41 overcomes the armature spring 45 to open contacts 47, 48 and so connect a resistor 50 in series with the winding 14 to reduce its current. Simultaneously, current flows through the coil 39 and resistors 35, 37, 38 to oppose the field of the coil 41 which upon reduction of the current in coil 14 and hence of the alternator voltage, is unable to overcome spring 45 and allows contacts 47, 48 to close, thereby starting the cycle of voltage control again. The current control is effected by the resistors 35, 37, 38 and coil 39 so that, with the alternator running at low speeds and only a weak air current available for cooling the rectifiers, the current through the latter is limited by the increase in resistance with temperature rise of the resistors 35, 37, 38 which reduces the current in the coil 39 and hence the field opposing the coil 41, thus reducing the voltage to which the alternator is controlled. At high speeds the current control adapts itself automatically to the increased load-carrying capacity of the rectifiers caused by the improved cooling and increases the voltage (and current) to which the alternator is controlled.
